Limit Switches - YAI
Promising Stable Operation Even in Adverse Environments
Yaskawa's BestactTM dustproof and flood-tight limit switches offer industry compatible mounting capability with IP52-IP68 (~NEMA 2-6) enclosure ratings. These switches utilize Yaskawa's world-renowned Bestact™ inductive rated (360VA, 0.5HP) reed switches. They do not need snubber, varistor, or diode protective devices for contact protection as other electromechanical and solid state switch products require. They are ideal for corrosive, dirty, extreme temperature, and gaseous Class I, Division 2 hazardous environments where reliability and reduced maintenance costs are of the utmost importance. Multi-pole options, two-line wiring, and other features are offered.

Specifications & Features
Limit Switches - Overview
Features
- Complete flood tight and gas resistance:
- Outstanding environmental immunity is assured by employing flood tight, corrosion-resistant construction and through use of heretically sealed contact
- Long-term maintenance free:
- This is achieved through the combination of the actuator exhibiting high mechanical strength as well as internal vane-action magnetic proximity switch featuring high electrical reliability, assuring long-term maintenance-free operation
- Powerful contact:
- Inductive load of 115VDC 0.3A can be directly controlled without using an amplifying relay or protective circuit
- No contact chattering:
- Since large actuator movement is considered in design, the switch is not ill affected by operational shock or vibration. Therefore, electrical circuit can be simplified
